This standard applies to x-ray equipment intended to be used for digital projection radiography and defines a set of minimum requirements designed to more easily facilitate quality control at the facility level. In particular@ items pertinent to the following quality control elements are contained within: a) Image quality analysis. b) Means to identify image processing settings and validate the consistency of image processing settings over time. This standard sets requirements for computed radiography (CR) and digital radiography (DR) equipment intended to be used for projection radiography. Equipment intended to be used for bone or tissue densitometry@ radiation therapy@ computed tomography@ fluoroscopy@ mammography@ or dental applications are excluded from the scope of this standard. The x-ray equipment falling under this standard is hereafter referred to as equipment.
